Aehr Test Systems Stock Gains on Follow-On Order for AI Chip Testing Equipment

Shares of Aehr Test Systems (AEHR) surged in early trading after the company announced it received another significant follow-on production order from a key customer. The semiconductor equipment maker's stock gained 6.2% in pre-open trading on the news, which investors see as confirmation of growing demand in the artificial intelligence and data center markets.

Order Signals Production Ramp

The order is for a fully automated FOX-XP multi-wafer production burn-in and testing system, according to a company statement. This marks the third such system ordered by its lead silicon photonics customer in 2026. Aehr noted the order follows the successful, fully automated production qualification of the customer's first system.

This milestone is critical for investors as it indicates the customer is now transitioning into high-volume manufacturing. The systems are used to test next-generation silicon photonic integrated circuits, which are essential components for:

• AI optical interconnects
• Hyperscale data center applications

While financial terms of the deal were not disclosed, the repeated orders underscore a strengthening relationship and growing production needs from a major client in a high-growth sector.

Building on Financial Momentum

The announcement adds to a series of positive developments for Aehr Test Systems. In mid-July, the company reported strong fiscal fourth-quarter results, including:

• Revenue: $18.8 million, an increase of 33% year-over-year.
• Earnings Per Share: $0.11, a significant improvement from a loss in the prior-year period.

Looking ahead, the company issued ambitious fiscal 2027 revenue guidance of $130 million to $150 million. This new order helps substantiate that outlook and reinforces investor confidence in the company's ability to capitalize on the build-out of AI infrastructure.
